Answer:

Step-by-step explanation:

Formula of Volume= $a^{3}$ - a = side

Therefore since the volume is given you just need to find the side.

729= $a^{3}$ = $\sqrt[3]{729}$ = a

= 9 = a

Now you know that 9 is the side, so using that find the area of one face-

Area of a square= 9 x 9 = 81 $cm^{2}$
